[PATCH] cpusets: remove depth counted locking hack
Remove a rather hackish depth counter on cpuset locking. The depth counter was avoiding a possible double trip on the global cpuset_sem semaphore. It worked, but now an improved version of cpuset locking is available, to come in the next patch, using two global semaphores. This patch reverses "cpuset semaphore depth check deadlock fix" The kernel still works, even after this patch, except for some rare and difficult to reproduce race conditions when agressively creating and destroying cpusets marked with the notify_on_release option, on very large systems.
